"Efecto de la utilización de varios niveles de harina de vísceras de pollo en lechones destetados sobre parámetros productivos"

Abstract

An experiment was carried out at the “Zambrano” farm, located in Cantón el Carmen, in the San Pedro de Suma parish. With the objective of evaluating the use of chicken viscera meal (HV) in weaned piglets on the productive parameters from 28 to 60 days of age. The viscera meal contains feathers, blood, viscera, legs, heads, etc., which derive from the slaughter of birds in the production systems, which are then processed in the by-products plant, they are transformed into raw materials of high protein value. 36 28-day-old male and female pigs were used to evaluate three treatments: T1 (100% PC-0% HV), T2 (50% PC-50% HV), T3 (0% PC-100% HV). The variables to be evaluated were: food consumption, average daily weight gain, food conversion, morbidity, mortality and profitability. The results did not show significant differences (p> 0.05) in body weight, weight gain, feed consumption and feed conversion. Consumption was higher for T3 (0.635) followed by T2 (0.586), at the end T1 (0.586). The feed conversion was lower for T1 (1.37) followed by T2 (1.46) and finally T3 (1.59). After conducting the economic analysis, it was determined that treatment T3 (0% PC-100% HV) was the most profitable in terms of production cost per kg of meat, followed by T2 (50% PC- 50% HV) and finally T1 (100% PC- 0% HV). It is concluded that chicken viscera meal can be used 100% in weaned piglets, prior preparation, due to its low production cost per kg of meat.
